Abstract

A colorimeter for converting a color output to an electrical signal, comprising a color chart (46) for comparing with a color (52, 54) which is to be converted, means (110) for generating an electrical signal which corresponds to a favorable comparison of the color to the color chart, and means (14) for locating the colors of the chart with respect to the means for generating an electrical signal so that the means for generating an electrical signal is conventiently located to be actuated when the color which is to be converted approximates a color on the chart, the means for generating an electrical signal comprising a plurality of switches (96-102), each having two states, means (112) responsive to the states of the switches for providing the electrical signal which corresponds to a favorable comparison of the color to the color chart, and means for coupling the electrical switches to the means for combining the states of the switches.
